Twenty years ago a friend and I were discussing how to make a cheap air compressor out of a lawn mower engine He said, that's easy. Remove the camshaft, remove the valve springs from both intake and exhaust valves and install much lighter springs on the valves. Install a check valve in the spark plug hole. Install about a 8-10" pulley on the crankshaft and drive it with a 1/3hp electric motor with a 3" pulley. Now when the piston starts it's downward stroke both valves suck open due to the light springs on the valves and slam shut on the start of the upward motion of the piston and push air out the spark plug hole. I ran this for 18 years with no problems It will put out about 100 lbs. pressure. It would be interesting if you could do that with a A12 engine. Or any multi cylinder engine. I know that using a V8 engine with running it on 4 cylinders, (every other one in the firing order) and using the other four for air works great.
